Plan HG-1644 (1,120 Sq Ft (28x40) 3 Bed 2 Bath Shop House (Shouse) Floor Plan with Shop) is an IRC R304/R310-vetted shop house (shouse) blueprint engineered around a 40'-0" × 28'-0" structural grid (1,120 sq ft base footprint, 0.7:1 Square-Bay Proportion). Configured on the Side-Bay Shop + Wet-Core Mudroom Buffer topology, this layout delivers 645 sq ft of conditioned residential living area paired with a 476 sq ft fire-separated workshop/garage bay and 184 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 6 distinct architectural zones: 1-BAY SHOP / GARAGE (17'-0" × 28'-0", 476 sq ft), PRIMARY SUITE (12'-0" × 12'-6", 150 sq ft), BEDROOM 2 (11'-0" × 12'-6", 138 sq ft), GREAT ROOM & DINING (13'-6" × 15'-6", 209 sq ft), BATH & MUDROOM (9'-6" × 7'-0", 67 sq ft), KITCHEN & ISLAND (9'-6" × 8'-6", 81 sq ft). Plumbing rough-ins are consolidated across BATH & MUDROOM, KITCHEN & ISLAND to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (PRIMARY SUITE at 150 sq ft; BEDROOM 2 at 138 sq ft) are acoustically buffered from the primary living core and positioned on exterior elevations for code-compliant egress glazing.

From a builder takeoff standpoint, the 40' clear-span width utilizes red-iron i-beam or heavy post-frame clear-span (14'–16' eave) bearing on 136 linear feet of 6" exterior wall framing (~164 framing studs/posts) and 113 linear feet of interior partitions. The 4:12 26-gauge galvalume / painted steel gable roof requires approximately 1,322 sq ft of roofing material (16 roofing squares), while the 6" 4000-psi fiber-mesh shop slab + 4" living slab pours at an estimated 25 cubic yards of 4,000-PSI concrete.

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 40x28 1,120 Sq Ft (28x40) 3 Bed 2 Bath Shop House (Shouse) Floor Plan with Shop (HG-1644)?

Based on current national residential construction data for shop house (shouse) structures, the dried-in structural shell for Plan HG-1644 (1,120 sq ft base footprint) ranges from $31,500 to $40,500 ($30/sq ft baseline). A complete turnkey build—including the 25-yard concrete foundation, 113 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 645 sq ft of heated space plus the 476 sq ft shop bay—ranges from $102,000 to $124,000. Use the interactive Regional Cost Multiplier on this page to adjust for your local labor market and owner-builder sweat equity.

What are the exact room dimensions inside this 645 sq ft 3-bedroom layout?

Plan HG-1644 features 6 architecturally solved spaces inside its 40' × 28' footprint: 1-BAY SHOP / GARAGE (17'-0" × 28'-0", 476 sq ft), PRIMARY SUITE (12'-0" × 12'-6", 150 sq ft), BEDROOM 2 (11'-0" × 12'-6", 138 sq ft), GREAT ROOM & DINING (13'-6" × 15'-6", 209 sq ft), BATH & MUDROOM (9'-6" × 7'-0", 67 sq ft), KITCHEN & ISLAND (9'-6" × 8'-6", 81 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 40' × 28' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 40'-0" × 28'-0" structural grid (136 LF perimeter) with clear-span 4:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for Red-Iron I-Beam or Heavy Post-Frame Clear-Span (14'–16' Eave), conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
